Immunocompetent Young Patient Presenting with Unilateral Lip Abscess Due to Peeling Exfoliated Lip Skin.

Lip abscess is a rare condition encountered in clinical practice. Generally, it may be due to an infective agent, such as virus, bacteria, entering through a skin wound, or it can be seen through hematogenous spread when there is a serious underlying condition such as a general condition disorder or immunodeficiency. It requires rapid diagnosis and treatment as it may cause significant complications in terms of localization and lymphovascular drainage.

Participants were classified into four categories based on WB-MRI findings, and those with relevant findings (i.

A practical approach to imaging characteristics and standardized reporting of COVID-19: a radiologic review.

Novel coronavirus (2019-nCoV), also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a pathogen that has caused a rapidly spreading pandemic all over the world. The primary mean of transmission is inhalation with a predilection for respiratory system involvement, especially in the distal airways. The disease that arises from this novel coronavirus is named coronavirus disease 2019 (COVID-19).
